Advanced Energy of North Carolina Study On New Heating & Cooling Units

  • 90% of all units tested exhibited some sort of energy waste problem
  • 50% of all installations had an improper refrigerant charge
  • 40% failed to meet the minimum requirements for air flow standards
  • A 20% reduction in air flow will reduce SEER about 17% (12/9, 14/9, 18/14)
  • A 15% return air leak from 120 degree attic will easily reduce a 12 SEER TO 6 SEER

APS (Arizona Public Service Company)

  • Improvements to duct leakage and insulation can save 16% on cooling cost
  • Properly insulated ducts and efficient units can reduce cooling usage by 42%
  • 64% of units tested had air flow less than 350 CFM per ton (Ideal CFM is 400)
  • 82% were improperly charged (average improper charge reduces efficiency 31%)
  • Installation technicians frequently do not evacuate a system properly with Micron Gauges
  • 53% of units tested were oversized causing wear and tear, and thus higher energy costs

Texas A&M University

  • A 15% savings can be observed when one disconnected duct was repaired
  • A 7.5% savings can be observed when diffuser air leakage was repaired
  • A 5.6% savings can be observed when air flow circulation was balanced correctly
  • A 18.4% savings can be observed when air leaks were sealed and refrigerant charges were correct

HVAC Manufacturers

  • A 13 SEER condenser mismatched with an existing air handler will typically lower SEER to 9.2, which is a 30% efficiency loss
  • Mismatched equipment, or replacing components in pieces and not installing the entire system new, typically will lower overall efficiency by as much as 30% and can void the manufacturer’s warranty
